KNOW YOUR UNIT

S Read your instruction manual carefully until

you completely understand and can follow all

warnings and safety rules before operating

the unit.

D Restrict unit to users who understand and will

follow all warnings and safety rules in this

manual.

WARNING: Inspect area before start-

ing unit. Remove all debris and hard objects

such as ro cks, g l ass, wi r e , etc. tha t can rico-

chet, be thrown, or otherwise cause injury or

damage during operation.

Use your unit as a blower for:

D Sweeping debris or grass clippings from

driveways, sidewalks, patios, etc.

D Blowing grass clippings, straw , or leaves into

piles, around joints, or between bricks.

Use your unit as a vacuum for:

D Pickingupdrymaterialsuchas leaves,grass,

small twigs, and bits of paper.

D For best results during vacuum use, operate

your unit at high speed.

D Move slowly back and forth over the material

as you vacuum. Avoid forcing the unit into a

pile of debris as this can clog the unit.

D Keep the vacuum tube about an inch above

th e gro u n d for best resu l ts.

PLAN AHEAD

D Always wear eye and ear protection when

operating, servicing, or performing

maintenance on unit. Wearing eye protection

will help to prevent rocks or debris from being

blown or ricocheting into eyes and face which

can result in blindness and/or serious injury .

Eye protection should be marked Z87.

D Always wear foot protection. Do not go

barefoot or wear sandals.

D Always wear respirator or face mask when

D Keep children, bystanders,and animals away

fromwork area aminimum of15 meters when

starting or operating unit. Do not point blower

nozzle in the direction of people or pets.

HANDLE FU EL WITH CAUTION

D Eliminate all sources of sparks or flame

(including smoking, open flames, or work that

can cause sparks) in the areas where fuel is

mixed, poured, or stored.

D Mix and pour fuel in an outdoor area; store

fuel in a cool, dry,well ventilatedplace; usean

approved, marked container for all fuel

pu r p o se s.

D Do not smoke while handling fuel or while

operating the unit.

D Make sure the unit is properly assembled and

in good operating condition.

D Do not fill fuel tank while engine is hot or

running.

D Avoid spilling fuel or oil. Wipe up fuel spills

before starting engine.

D Move at least 3 meters away from fuel and

fueling site before starting engine.

D Always store petrol in a container approved

for flammable liquids.

OPERATE Y OUR U NIT SAFELY

WARNING: Stop the engine before

opening the vacuum inlet door . The engine

must be stopped and the impeller blades no

longer turning to avoidserious injury from the

rotating blades.

D Inspect unit before each use for worn, loose,

missing, or damaged parts. Do not use until

unit is in proper working order.

D Keep outside surfaces free of oil and fuel.

D Never start or run engine inside a closed

room or building. Breathing exhaust fumes

can kill.

D Muf flers fitted with catalytic converters get

very hot during use and remain so for some

time after stopping. This also applies at idle

speed. Contact can result in burns to theskin.

Remember the risk of fire!

D To avoid static electricity shock, do not wear

rubber gloves or any other insulated gloves

while operating unit.

D Do notsetuniton any surface exceptaclean,

hard area while engine is runnin g. Debris

property, or causing serious injury to

bystanders or operator.

D Avoid dangerous environments. Donot use in

unventilated areas or where explosive vapors

or carbon monoxide build up could be

present.

D Do not overreach or use from unstable

surfaces such as ladders, trees, steep

slopes, rooftops, etc. Keep firm footing and

balance at all times.

D Never place objects inside the blower tubes;

always direct the blowing debris away from

people, animals,glass, andsolid objects such

as trees, automobiles, walls, etc. The force of

air can cause rocks, dirt, or sticks to be

thrown or to ricochet which can hurt people or

animals, break glass, or cause otherdamage.

D Never run unit without the proper equipment

attached. When using your unit as a blower ,

always install blower tubes. When using your

unit as a vacuum, always install vacuum

tubes and vacuum bag assembly. Make sure

vacuum bag assembly is completely zipped.

D Check air intake opening, blower tubes,

vacuum tubes, and elbow tube frequently,

always with engine stopped and spark plug

disconnected. Keep vents and discharge

tubes free of debris which can accumulate

and restrict proper air flow.

D Never place any object in the air intake

opening as this could restrict proper air flow

and cause damage to the unit.

D Never useforspreading chemicals,fertilizers,

or other substances which may contain toxic

materials.

D Toavoidspreadingfire, donot usenear leaf or

brush fires, fireplaces, barbecue pits,

ashtrays, etc.

D Use only for jobs explained in this manual.

OPERATING TIPS

S While vacuuming or blowing debris, hold

the unit with the muffler side facing away

from your body and clothes (seeOPERA T-

ING POSITION).

S To reduce the risk of hearing loss

associated with sound level(s), hearing

protection is required.

S To reduce the risk of injury associated with

contacting rotating parts, stop the engine be-

fore installing or removing attachments. Do

not operate without guard(s) in place.

S Operate power equipment only at reasonable

hours--not early in the morning or late at night

when people might be disturbed. Comply with

times listed in local ordinances. Usual recom-

mendations are 9:00 a.m. to 5:00 p.m.,

Monday though Saturday.

S To reduce noise levels, limit the number of

pieces of equipment used at any one time.

S To reduce noise levels, operate power

blowers at the lowest possible throttle

speed to do the job.

S Userakes andbrooms toloosen debris be-

fore blowing.

S In dusty conditions, slightly dampen sur-

faces or use a mister attachment whenwa-

ter is available.

S Conserve water by using power blowers

instead of hoses for many lawn and garden

applications, including areas such as gutters,

screens, patios, grills, porches, and gardens.

S Watchoutfor children,pets, openwindows,

or freshly washed cars. Blow debris away

safely.

S Usethe full blower nozzle extension so the

air stream can work close to the ground.

S After using blowers and other equipment,

CLEAN UP! Dispose of debris in trash re-

ceptacles.

BEFORE STARTING ENGINE

WARNING: Be sure to read the fuel

information in the safety rules before you

begin. If you do not understand the safety

rules,donotattempttofuelyourunit. Contact

an authorized service dealer.

FUELING ENGINE

WARNING: Remove fuel cap slowly

when refueling.

This engine is certified to operate on

unleaded petrol. Before operation, petrol

must be mixed with a good quality 2-cycle

air-cooled engine oil. We recommend

McCulloch brand oil mixed at a ratio of 40:1

(2.5%). A 40:1 ratio is obtained by mixing 5

liters of unleaded petrol with 0,125 liter of oil.

When mixing fuel, follow the instructions

printed on the container. Always read and

followthesafetyrules beforefuelingyourunit.

IMPORTANT

fuels (called gasohol or using ethanol or

methanol)canattractmoisturewhichleadsto

than 10 minutes without being used, it will be

necessary to start the unit by following the

steps under STAR TING A COLD ENGINE or

following the starting instruction steps shown

on the unit.

STARTING A FLOODED ENGINE

Flooded engines can be started by moving the

start lever to the RUN position and fully

squeezing the throttle trigger. Pull the starter

handle repeatedly while squeezing throttle

triggeruntil enginestarts andruns.This could
